How to Factory Reset iPhone 12

Factory resetting your iPhone 12 wipes all your data and settings, bringing it back to its original state. This can be useful if you’re troubleshooting issues, preparing to sell your device, or simply wanting a fresh start. To do this, go to Settings, select General, tap Reset, and choose Erase All Content and Settings. Confirm your choice, and your iPhone will restart with everything removed.

How to Factory Reset iPhone 12

Factory resetting your iPhone 12 will erase every bit of data, from apps and photos to personal settings, allowing your device to start fresh as if it just came out of the box.

Step 1: Backup Your Data

Before resetting, connect your device to a computer or iCloud to save important files.

Backing up ensures you don’t lose important memories or documents. Use iCloud for a wireless backup or iTunes if you prefer a wired connection.

Step 2: Open Settings

Unlock your iPhone and tap the gray gear icon to access Settings.

Settings is your go-to place for managing your device. The icon is usually found on your home screen or app library.

Step 3: Tap General

Scroll down the Settings menu and select General.

The General section houses many fundamental options for controlling your iPhone’s behavior and functioning.

Step 4: Select Reset

In the General menu, scroll to the bottom and tap Reset.

Reset options let you manage different levels of resetting, from network configurations to a full system wipe.

Step 5: Choose Erase All Content and Settings

Tap Erase All Content and Settings and confirm your decision.

This action will trigger the factory reset, wiping everything off your device. Make sure you’re ready, as this can’t be undone.

After completing these steps, your iPhone will restart, and you’ll see the Apple logo. Once booted, the setup screen will appear, ready for you to start anew or restore from backup.
